Hi!
I have not tried the over scan correction with the latest drivers, which I have had trouble with, as well, with flats. Luminance will calibrate ok, but RGB will be lighter on the bottom half of the picture and darker on the top.
I upgraded my machine to Win7 Ultimate, which is why I was using the latest drivers. While trying to help another IIS member with some data collection problems, my QHY9 and filter wheel shut down. Theo was great at helping me sort out the problems with it and it is working again. The problem appears to be that the connector on the power supply that came with the camera is 2.5mm and the dual cable is 2.1mm. That is all fixed now, with a trip to Jaycar.
The result of all this is that I have regressed my drivers to the original that came with the camera and the flats problem is now fixed.
The problem that I now have is that all my binned shots have horizontal lines about a 10mm apart. I have changed power supplies, so I will change back and see.
Oh, and I'm using MaxIm 5.
